Testing .5ohm

Get a dual 1 sub and run it at .5 ohm.

What does your electrical consist of

130 amp alt with duralast platinum battery. My voltage never really drops below 13.3 -13.4. I am also not looking to demo for an hour straight. I never really play full tilt for more than 3 songs.

You wont even last 5 mins at full tilt.

What size is your front battery? And im assuming its a agm? What size power wire? Cca or ofc?

big three one battery in the trunk everything is cca because all runs are less 2 feet. the run from the alt to the battery is ofc battery is 100ah agm

Give it a shot and report back. I myself never do .5 but to each

Only way to test is to run something.at the very least you'll need another battery.so save up for a sub and battery

Well I am selling my subs to buy new ones but should I risk it and get 2 d2s instead of d4s? If my system cant handle it and cant even play full tilt one song cant I just not play full tilt until I get d4s?

Turn the gain down.. Easy as that

Exactly. That amp will run at .25 ohm even, but it'll tank your voltage quick. It will run fine at a lower impedance as long as it has the proper amount of current available. If you find your voltage dropping too low, turn the gain down. Most folks who blow their equipment running a low impedance do so by not readjusting their gain and not paying attention to their voltage.

This thread is full of terrible advice. You can have 100 batteries and running low impedance is still risky. A good rule of thumb is that if you have to ask and/or can't afford to buy a new amp tomorrow, don't try to run below what load manufacturer recommends.

You test at .5 ohm or lower when you have great electrical along with spare amps and just dont give a F

3 D3100's from XS could hold up for a while on a daily, but that alternator would be stressing big time.
@hispls If he could afford 100 batteries he would have just purchased the largest alt or 2 and add 2 large batteries.
Running .5 ohm is not rocket science, the fact that he doesnt have the electrical is another thing. Most who ruin amps due to .5 ohm are either testing a new amp or an amp that has not been test at that ohm rating.

OR they run them below voltage limit.
